Bitcoin Treasury Company

What Is a Bitcoin Treasury Company?

A Bitcoin treasury company is a publicly traded corporation that allocates a significant portion of its balance sheet to bitcoin as a primary reserve asset. Unlike companies that might hold small amounts of cryptocurrency incidentally, a Bitcoin treasury company adopts a formal treasury reserve policy designating bitcoin as a core holding. The strategy treats bitcoin as digital gold: a scarce, durable, globally liquid asset that can serve as an inflation hedge and long-term capital preservation tool.

The concept was pioneered by MicroStrategy (now rebranded to Strategy) in August 2020, when CEO Michael Saylor announced the company had purchased 21,454 BTC for $250 million. Saylor argued that holding cash was a losing strategy due to monetary expansion and currency debasement, and that bitcoin's fixed supply of 21 million coins made it a superior treasury reserve. What began as an unconventional bet by a single mid-cap software company has since grown into a corporate movement spanning hundreds of firms across multiple countries and industries.

How It Works

Bitcoin treasury companies follow a general playbook for acquiring and managing bitcoin on their corporate balance sheets. While specifics vary, the core mechanics are consistent across the category.

Capital Acquisition Strategy

Most Bitcoin treasury companies do not fund bitcoin purchases from operating cash flow alone. Instead, they raise capital through a combination of instruments:

• At-the-market (ATM) equity offerings: selling newly issued shares at prevailing market prices to fund bitcoin purchases
• Convertible notes: issuing debt that converts to equity at a premium, often at 0% interest, where investors accept zero coupon in exchange for bitcoin price exposure
• Preferred stock: issuing dividend-paying preferred shares, as Strategy did with its STRK and STRF instruments

This approach creates a leveraged bitcoin exposure: if bitcoin appreciates faster than the dilution from new share issuance, existing shareholders benefit. The key metric these companies track is "BTC Yield," defined as the percentage change in bitcoin holdings per diluted share outstanding over a given period.

FASB Fair Value Accounting

Before 2025, a major obstacle to corporate bitcoin adoption was accounting treatment. Under prior US GAAP rules, bitcoin was classified as an indefinite-lived intangible asset subject to impairment-only accounting. Companies had to write down bitcoin's value whenever the market price fell below their cost basis, but could never write it back up even if prices fully recovered. This created an asymmetric penalty: losses appeared on income statements, but gains did not.

In December 2023, the Financial Accounting Standards Board (FASB) issued ASU 2023-08, requiring fair value measurement for qualifying crypto assets. Under the new standard, companies report bitcoin at its current market price each quarter, with both gains and losses flowing through net income. The rules took effect for fiscal years beginning after December 15, 2024, meaning most calendar-year companies began applying them in January 2025.

The impact was significant: fair value accounting removed the asymmetric penalty that discouraged corporate bitcoin holdings. However, it also means that quarterly earnings now fully reflect bitcoin's volatility, which can produce dramatic swings in reported profits and losses.

NAV Premium and mNAV

A critical concept for Bitcoin treasury companies is the multiple of net asset value (mNAV): the ratio of a company's market capitalization to the market value of its bitcoin holdings. When a company trades at an mNAV above 1.0, its stock is valued at a premium to its bitcoin. When mNAV falls below 1.0, the stock trades at a discount.

The mNAV premium matters because it determines whether new bitcoin acquisitions are accretive or dilutive. When a company trades at 2x mNAV, it can issue $1 of stock to buy $1 of bitcoin while only giving up $0.50 of economic value per share. When the premium collapses, this mechanism reverses: new issuance dilutes existing shareholders without proportional bitcoin accumulation.

Notable Bitcoin Treasury Companies

Strategy (formerly MicroStrategy)

Strategy is the largest and most prominent Bitcoin treasury company. The firm rebranded from MicroStrategy in February 2025 to signal its transformation from a business intelligence software vendor to a bitcoin-focused financial vehicle. Under Executive Chairman Michael Saylor, the company has accumulated over 800,000 BTC through a combination of ATM equity offerings, convertible notes, and preferred stock instruments, raising over $25 billion in capital during 2025 alone.

Strategy's stock (MSTR on NASDAQ) peaked at an mNAV of approximately 3.4x in November 2024, before compressing below 1.0x during mid-2026 as bitcoin declined from its highs. In 2026, the company broke its longstanding "never sell" policy for the first time since 2022, selling small amounts of bitcoin to fund preferred stock dividends.

Metaplanet

Listed on the Tokyo Stock Exchange, Metaplanet has been called "Asia's MicroStrategy." The company pivoted from struggling hospitality operations to a bitcoin treasury strategy, accumulating over 35,000 BTC by end of 2025. Metaplanet has cited Japan's debt-to-GDP ratio (exceeding 260%) and persistent yen depreciation as motivation for holding bitcoin rather than yen-denominated reserves.

Twenty One Capital

Twenty One Capital (XXI) launched in late 2025 as a purpose-built Bitcoin treasury company, backed by Tether ($1.5 billion), SoftBank ($900 million), and Bitfinex ($600 million). Led by Strike founder Jack Mallers, the company began trading on the NYSE in December 2025 with over 43,000 BTC, making it the third-largest public corporate bitcoin holder at launch.

Other Notable Holders

Several other public companies maintain significant bitcoin treasuries:

• Tesla: purchased $1.5 billion in bitcoin in early 2021, sold roughly 75% in 2022, and has held approximately 11,500 BTC since late 2022 with no additional purchases or sales
• Block (formerly Square): holds approximately 9,000 BTC as corporate treasury, with broader bitcoin exposure through Cash App and mining hardware initiatives
• GameStop: approved a bitcoin treasury policy in 2025 and raised $3.75 billion through convertible note offerings to fund purchases
• Bitcoin miners such as Marathon Digital and Riot Platforms also held significant treasuries, though several miners have sold portions during 2026 to fund operations or pivot toward AI infrastructure

Why It Matters

The Bitcoin treasury company trend represents one of the most significant institutional adoption vectors for bitcoin. By 2026, over 170 public companies held bitcoin on their balance sheets, with combined corporate holdings exceeding 1.2 million BTC: over 6% of bitcoin's total 21 million supply cap. Corporate bitcoin buying was running at roughly 2.8 times daily mining output in early 2026, creating substantial demand pressure independent of retail Bitcoin ETF flows.

The corporate treasury movement also parallels and reinforces sovereign adoption. The United States established a Strategic Bitcoin Reserve via executive order in March 2025, while countries like El Salvador and Bhutan have built national bitcoin reserves through different mechanisms. Corporate treasuries collectively hold far more bitcoin than all nation-states combined, but sovereign legitimization has further encouraged corporate adoption.

For companies and developers building on Bitcoin, the treasury trend increases demand for secure cold storage, multisig custody solutions, and institutional-grade infrastructure. Layer 2 networks and stablecoin protocols benefit from increased corporate interest in the broader Bitcoin ecosystem, as treasury companies often expand into adjacent products and services.

Risks and Considerations

Volatility Exposure

Bitcoin remains a volatile asset, and companies with concentrated bitcoin treasuries amplify that volatility through leverage. When bitcoin declined from its late-2025 highs, Strategy reported a $12.5 billion loss in a single quarter. Under FASB fair value rules, these losses flow directly through earnings, creating significant quarter-to-quarter swings that can alarm investors and trigger margin pressures.

NAV Premium Collapse

The bitcoin treasury model works well when a company trades at a premium to its bitcoin NAV, because share issuance is accretive. When the premium evaporates or inverts to a discount, the flywheel reverses: new share issuance dilutes existing holders without proportional benefit. Strategy's mNAV declined from approximately 3.4x to below 1.0x over the course of 2025 and 2026, illustrating how quickly the premium can erode.

Concentration and Liquidity Risk

Companies that allocate most of their balance sheet to a single asset face concentration risk. If bitcoin enters a sustained bear cycle, treasury companies may need to sell bitcoin to meet debt obligations, fund dividends, or maintain operations: precisely the scenario the "never sell" narrative is designed to avoid. By mid-2026, at least 20 public bitcoin treasury companies had fully liquidated, reduced, or abandoned their accumulation strategies due to market pressures, debt obligations, or business pivots.

Shareholder Dilution

Continuous equity issuance to fund bitcoin purchases dilutes existing shareholders. The BTC Yield metric attempts to capture whether dilution is offset by bitcoin accumulation, but it only works when bitcoin appreciates. In flat or declining markets, shareholders bear both dilution and price depreciation.

Regulatory Uncertainty

Digital asset regulation continues to evolve across jurisdictions. Changes in tax treatment, securities classification, or custody requirements could affect the viability of bitcoin treasury strategies. The interaction between fair value accounting and tax reporting also creates complexity: unrealized gains reported under FASB rules may not align with tax obligations in all jurisdictions.
